JOSIAH A. DEWEY, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO DEWEY DAVENPORT COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.

FOLDING BED.

Specification of Letters Patent.

Patented June 12, 1917.

To all whom it may concern:

Be it known that I, JOSIAH A. DEWEY, a citizen of the United States, and a. resident of the city and county of San Francisco, State of California, have invented a certain new. and useful Folding Bed, of which the following is a specification.

The invention relates to that type of folding bed generally known as the davenport or sofa bed.

An object of the invention is to provide an easily operated folding bed.

Another object of the invention is to provide a folding bed of simple and sturdy construction and which possesses a high degree of comfort when used either as a sofa or a bed.

A further object of the invention is to I provide a folding bed in which the mattress frames or supports are independently movable in one position and conjointly movable in another position.

The invention possesses other advantageous features, some of which, with the foregoing, wili be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings, I have shown, one specific form of my generic invention, but it is to be understood that I do not limit myself to such form because my invention may be embodied in a multiplicity of forms, each being a species of my said invention. It is also to be understood that by the claims succeeding the description of my invention, I desire to cover the invention in whatever form it may be embodied.

Referring to said dra'wingsr Figure 1 is a cross section ofthe bed of my invention in the folded position.

Fig. 2 is a similar view showing the bed partly unfolded, the bed springs and upholstery being removed. Fig. 3 is a similar view showing the bed in the unfolded or extended position.

Fig. 4 is a top or plan view of one side of the structure in the extended position.

Fig. 5 is a longitudinal vertical section of one end of the structure showing the looking means for the lower bed frame bodied in a box couch, but it is evident that the inclosing frame may be made in the davenportstyle or otherwise. In its present embodlment, the invention comprises a stationary structure having a back 2, sides 3 and front board 4:. Arranged in the structure is a lower bed frame comprising the rectangular frame 5 upon which the coiled spr ngs 6 are mounted, the upper ends of which springs are joined by a suitable flexible structure 7 upon which the upholstered mattress rests. The lower bed frame is normally disposed at the bottom of the structure. Secured to the sides 3 at opposite ends of the structure are guides 8-9 preferably vertically arranged, which may be formed of channel irons, the channels being closed at their lower ends. Secured to the frame 5 and engaging in said guides are slides 1213, which preferably extend above the frame 5. The slides preferably consist of angle irons having one leg bolted to. the frame 5 and the other lying in the groove of the channel and when the frame is in the depressed position the slides engage the closed lower end of the channels, supporting the lower frame. The slides are of such length that they will not bind in the ides.

Arranged in superposed relation with respect to the lower bed frame, when the bed is folded, is the upper bed frame, composed of the rectangular frame 14 upon which are mounted the coil springs 15, which are con-.

nected together at their free ends by a suitable flexible structure 16. 'When the bed is folded, the upper bed frame is inverted, and in the present structure, sufficient space is left between the flexible structures 7 and 16 of the spring mattress to accommodate a double or folded upholstered mattress. On the upper sideof frame 14 is arranged a suitably upholstered seat 17. v

The upper frame- 14 is pivoted adjacent its forward side by pivots 18 arranged in or secured to the sides 3. The pivots 18 are.

preferably stationary and are engaged by plates 19 secured to the opposite ends of the frame 14: at the forward side. The position of the pivots 18 and the height of the back 2 are related so that when the upper frame is folded it lies in the horizontal osition. The upper frame is movable from 1ts horizontal folded position through an arc of 180 degrees to its extended horizontal position.

Means are'provided for allowing the upper frame 14 to rotate independently of the lower frame 5, through a given are from its horizontal folded position and for causing the further unfolding movement of the upper frame to be accompanied by a raising movement of the lower frame, so'that the two frames are moved into alinement as they reach their unfolded or extended position. By means of'this partly independent and partly-conjoint movement of the bed frames, the bed is easily unfolded, since it is only necessary to raise the upper frame. The conjoint movement does not begin until after the upper frame has reached its vertical position, and the downward .movement of the frame is accompanied by an upward movement of the lower frame. The connections between the frames are such that the weight of the descending frame is counterbalanced by the weight of the ascending frame,jfimaking the bed very easy of operation.

Attached to the lower frame 5 at the centers of the opposite ends are links '21 which are connected at their free ends to links 22 pivoted to the plates 19, by pivots 23 spaced from the pivots 18... fThe pivots 23 and 18 on each plate are so arranged with relation to each other that the link 22 contacts with the pivot 18 at a point intermediate between the ends ofthe link when the upper frame 14 reaches or passes its vertical position in its unfolding movement. Thelink 22 is thereb converted into a lever with its fulcrum at tile pivot 18 and the further downward movement of frame 14 causes the lever 22 to move-the lower frame upwardly in its guides 8-9, to a position of alinement with the unfolded u per frame. Legs 24 pivoted .to the upper rame swing downward into contact with the fioor and support the outer end of the unfolded upper frame:

Means are provided for locking the lower frame in its elevated position. Arranged on the sides 3 above the guides 89 are spring pressed latches 25-26, the bolts 27 of which lie in the planes of, the guides 8--9. Each slide 1213 is provided with a seat 28, which when the lower frame is elevated, is engaged by said bolts,-holdin the frame in its raised position. Connecte to the bolts is a cord 29 which extends along the outer side of the lower frame when the bed is unfolded and by pulling onthis cord, the latches are released and the bed may be folded.

Means are also provided for assisting in 31, the free end of which presses against the under sideof the frame, tending to raise it. I claim: 1. In furniture of the class described, two

superposed bed frames, th upper frame being pivotally supported adjacent its forward side and being movable about said pivot through a redetermined are independent of the lower f i'ame, and means including a link pivoted to said upper frame at a point outside the pivotal axis of said framaand operative by the further movement of the upper frame for moving the lower frame.-

2. In furniture of the class described, a lower bed frame, an upper bed frame arranged 'in superposed relation therewith, pivots supporting the upper frame at its forward side, a link pivotally connected at} each end of the lower frame at the center'and a link connecting each of said center linksjwith the upper frame, said last named links being convertible into supporting levers for said lower frame as the upper bed frame is moved about its pivot.

3. In furniture of the class described, a

lower bed frame adapted to be raised, an

upper bed frame arranged in superposed relation with said lower frame adapted to be rotated about a horizontal axis, and links.

ent of the lowerframe and the further movelower bed frames whereby the downward.

movement only of the upper frame causes an upward movement of the lower frame and the upward movement only of the upper frame causes'a downward movement of the lower frame.

5. In furniture of the class described, a stationary structure, guides arranged on said structure, a lower bed frame movable in said guides, an upperbed rame arranged above said 'lower bed frame and pivoted tosaid structure, links connected to said lower frame, and links connecting said first named links with the upper bed frame, said second links being arranged to engage the pivots of the upper frame after the upper frame has been moved past the vertical posi-- tion in its unfolding movement.

upwardly movable lower bed frame, a pivoted upper bed frame arranged to be moved through a vertical are from the folded to the unfolded position, means connecting said bed frames operative by the descending movement only of said upper frame to raise the lower frame and by the descending movement of the lower frame to raise the upper frame, and means for locking the lower frame in its raised position.

7 In furniture of the class described, a stationary structure, an upwardly movable lower bed frame arranged in said structure, a pivoted upper bed frame arranged to be moved through a vertical are from a folded to an unfolded position, links connecting said frames operative by the downward movement of the upper frame to raise the lower frame and by the downward movement of the lower frame to raise the upper frame, means on said stationary structure for locking the lower frame in its raised position, and means for releasing said locking means.

&

8. In furniture of the class described, a stationary structure, guides secured to said structure, a lower bed frame arranged in said structure, slides on said frame engaging in said guides, an upper bed frame pivoted to said structure adjacent its forward side, links connecting said lower frame with the upper frame at points spaced from said piv-- ots, the pivotal point of the link and the pivot of the upper frame being so arranged that the links engage said pivots during the rotation of the upper frame, the further movement of the upper frame serving to raise the lower frame, and latches adapted to engage said slides and lock the lower frame in the raised position.

In testimony whereof, I have hereunto set my hand at San Francisco, California, this 19th day of January, 1915.
